ACTUATOR HAVING AN ADJUSTABLE RUNNING TIME
First Claim
1. An actuator system for a heating, ventilating and air conditioning (HVAC) system, comprising:
- a motor;
a gear train mechanically connected to the motor and having an HVAC actuator shaft;
a processor connected to the motor; and
a shaft position indicator connected to the gear train and to the processor; and
wherein;
the actuator shaft is rotatable a first number of degrees from a first position to a second position and a second number degrees from a third position to a fourth position;
a time for the actuator shaft to rotate the first number of degrees from the first position to the second position is a first running time;
a time for the actuator shaft to rotate the second number of degrees from the third position to the fourth position is a second running time; and
the first and second running times are separately adjustable.

Abstract
An actuator system having an actuator with a rotatable shaft. The shaft may have a first running time to rotate from a first position to a second position in one direction. The shaft may have a second running time to rotate from a first position to a second position in another direction. The first and second running times may be separately adjustable. A motor may be connected through a gear train to the rotatable shaft. A processor may control a rotation of the motor and thus the running times of the shaft. The running times may be adjusted with signals to the processor from a remote controller connected to the processor via a communications bus.
